Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Gas chromatography of isomeric pentyl halides.Formula: C5H11I.

Isomeric pentyl halides were separated by gas chromatog. Two columns were used: a 4 m. × 1/16-in. outer diameter stainless steel column packed with 10% squalane on 80-100-mesh Chromosorb W, N as the carrier at 13-15 ml./min. (column 1), and a 4-m. × 1/8-in. outer diameter stainless steel column packed with 11.5% Bentone 34 + 11.5% silicone MS 555 on 80-100-mesh Chromosorb W, N as the carrier at 25-30 ml./min. (column 2). On column 1, chlorides were analyzed at 20°, bromides and iodides at 40°; on column 2, all analyses were at 40°. A flame ionization detector was used with both columns. tert-Pentyl bromide and iodide decomposed in column 2 although not on column 1. The 3-halogenopentanes were the only isomers that could not be completely separated from all other pentyl structures.

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).HPLC of Formula: 616-14-8. 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.

Substances of the type MeCH[(CH2)n1X][(CH2)n2R], where n1 or n2 = 0 or an integer, X = a functional group and R = a normal alkyl, Ph or C6Hn group, can be classified into 2 categories, viz., those, typified by X = CHO, in which the configuration of the 1st members having n1 = 0 can be correlated by classical methods to those having n1 > 0, and those, typified by X = halogen, in which such correlation cannot be accomplished by classical methods. For the purpose of solving the latter problem the azides were chosen over the halides, inasmuch as they can be converted into the corresponding amines. The amines, while belonging to the 2nd category, can be correlated among themselves by a sufficiently reliable though nonclassical argument which will be reported later. The secondary azides were prepared by the action of NaN3 on the iodides and the amines by reduction of the azides with PtO2. The rotatory phenomena observed in the series of azides and halides were compared with those in the series of aldehydes and were found to be dissimilar in both series. Hence a comparison of these phenomena cannot be used for the correlation of the members of the series of halides and azides having n1 = 0 with those having n1 > 0.
