The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Vital signs: trends in use of long-acting reversible contraception among teens aged 15-19 years seeking contraceptive services—United States, 2005-2013.》. Authors are Romero, Lisa; Pazol, Karen; Warner, Lee; Gavin, Lorrie; Moskosky, Susan; Besera, Ghenet; Loyola Briceno, Ana Carolina; Jatlaoui, Tara; Barfield, Wanda; Centers for Disease Control and Prevention (CDC).The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).Quality Control of 1-Iodo-2-methylbutane. Through the article, more information about this compound (cas:616-14-8) is conveyed.

BACKGROUND: Nationally, the use of long-acting reversible contraception (LARC), specifically intrauterine devices (IUDs) and implants, by teens remains low, despite their effectiveness, safety, and ease of use. METHODS: To examine patterns in use of LARC among females aged 15-19 years seeking contraceptive services, CDC and the U.S. Department of Health and Human Services’ Office of Population Affairs analyzed 2005-2013 data from the Title X National Family Planning Program. Title X serves approximately 1 million teens each year and provides family planning and related preventive health services for low-income persons. RESULTS: Use of LARC among teens seeking contraceptive services at Title X service sites increased from 0.4% in 2005 to 7.1% in 2013 (p-value for trend <0.001). Of the 616,148 female teens seeking contraceptive services in 2013, 17,349 (2.8%) used IUDs, and 26,347 (4.3%) used implants. Use of LARC was higher among teens aged 18-19 years (7.6%) versus 15-17 years (6.5%) (p<0.001). The percentage of teens aged 15-19 years who used LARC varied widely by state, from 0.7% (Mississippi) to 25.8% (Colorado). CONCLUSIONS: Although use of LARC by teens remains low nationwide, efforts to improve access to LARC among teens seeking contraception at Title X service sites have increased use of these methods. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Health centers that provide quality contraceptive services can facilitate use of LARC among teens seeking contraception. Strategies to address provider barriers to offering LARC include: 1) educating providers that LARC is safe for teens; 2) training providers on LARC insertion and a client-centered counseling approach that includes discussing the most effective contraceptive methods first; and 3) providing contraception at reduced or no cost to the client.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Metal-free C(sp3)-H functionalization of sulfonamides via strain-release rearrangement, published in 2021, which mentions a compound: 616-14-8, mainly applied to unsaturated imine preparation diastereoselective chemoselective DFT; fluorotosylamide tosylbenzaldimine carbon hydrogen functionalization strain release rearrangement, Reference of 1-Iodo-2-methylbutane.

A metal-free reaction system that enables C-H bond functionalization of aliphatic sulfonamides R(CH2)2N(F)Ts (R = decyl, cyclohexyl, oxan-4-yl, benzyl, etc.) using DABCO as a promoter under mild conditions, affording a series of α,β-unsaturated imines R1CH=C(R)CH=NTs (R1 = Ph, 4-chlorophenyl, 2,3-dihydro-1-benzofuran-5-yl, etc.) in good yields with high selectivities was presented. This protocol tolerates a broad range of functionalities and can serve as a powerful synthetic tool for the late-stage modification of complex compounds More importantly, control experiments and detailed DFT calculations suggest that this process involves [2 + 2] cyclization/ring-cleavage reorganization, which opens up a new platform for the establishment of other related reorganization reactions.

Formula: C4H6N4O2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-Methyl-4-nitro-1H-imidazol-5-amine, is researched, Molecular C4H6N4O2, CAS is 4531-54-8, about Development of a HPLC-DAD stability-indicating method and compatibility study of azathioprine and folic acid as a prerequisite for a monolayer fixed-dose combination. Author is Brusac, Edvin; Jelicic, Mario-Livio; Amidzic Klaric, Daniela; Nigovic, Biljana; Keser, Sabina; Mornar, Ana.

Adherence in chronic diseases is a major problem which can be combated by prescribing fixed-dose combinations in the therapy of the disease. Thus, a combination of azathioprine and folic acid in the treatment of inflammatory bowel disease is highly required, but prior to formulation development, chem. compatibility of the two drugs needs to be investigated. In this work, differential scanning calorimetry, isothermal stress testing, in vitro dissolution and forced degradation studies were utilized to investigate compatibility. Moreover, a stability-indicating HPLC-DAD method for the determination of parent drugs and five of their impurities was developed, validated and applied to the inhouse sample. Compatibility testing revealed no noteworthy interactions of the two drug substances. Furthermore, forced degradation showed no substantial differences between the degradation profiles of each active pharmaceutical ingredient, their mixture and the inhouse sample, further reinforcing the claim of compatibility. Lastly, the inhouse sample was analyzed: it was shown to conform to the requirements of relevant regulatory documents for all the investigated analytes, demonstrating the method’s viability for use in formulation and process development. Our results give way to the possibility of realization of said fixed-dose combination.

There is still a lot of research devoted to this compound(SMILES：NC1=C([N+]([O-])=O)N=CN1C)Formula: C4H6N4O2, and with the development of science, more effects of this compound(4531-54-8) can be discovered.
