628-46-6 Usage

Description

5-Methylhexanoic acid, also known as iso-hexanoic acid, is an organic compound with a molecular formula of C7H14O2. It has a fermented cheese odor and is a monocarboxylic acid with a methyl group attached to the second carbon atom in the carbon chain.

Uses

Used in Ion-Exclusion Chromatography:
5-Methylhexanoic acid is used as an eluent in ion-exclusion chromatographic separations of C1-C6 aliphatic carboxylic acids on a sulfonated styrene-divinylbenzene co-polymer resin column. Its unique properties allow for high sensitive conductimetric detection, making it a valuable component in analytical chemistry for the separation and detection of various carboxylic acids.

Hazard

A reproductive hazard.

Check Digit Verification of cas no

The CAS Registry Mumber 628-46-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 628-46:
(5*6)+(4*2)+(3*8)+(2*4)+(1*6)=76
76 % 10 = 6
So 628-46-6 is a valid CAS Registry Number.

Rhodium(I) acetylacetonato complexes with functionalized phosphines

Pruchnik, Florian P.,Smolenski, Piotr,Wajda-Hermanowicz, Katarzyna

, p. 63 - 69 (2007/10/03)

Rhodium(I) complexes [Rh(acac)(CO)(PR3)] with 1,3,5-triaza-7-phosphatricyclo[3.3.1.13,7]decane (tpa), tris(2-cyanoethyl)phosphine (cyep), tris(3-sodium sulfonatophenyl)phosphine (tppts), tris(o-methoxyphenyl)phosphine (ompp), tris(p-methoxyphenyl)phosphine (pmpp), tris(2,4,6-trimethoxyphenyl)phosphine (tmpp), PPh2(pyl), PPh(pyl)2 and P(pyl)3 (pyl=2-pyridyl) have been synthesized and characterized with 1H- and 31P-NMR and IR spectra. The measured 31P coordination chemical shifts, Δδ31P{1H}, correlate well with ν(CO). Differences in 1H chemical shifts of methyl groups of acac ligand, ΔδMe, depend both on steric and electronic properties of phosphine ligand. Thus ΔδMe increases with decrease of Δδ31P{1H} and increases with increase of the cone angle of phosphine. Catalytic activity of complexes with tpa, cyep and tppts has been investigated. They are efficient catalysts for hydrogenation of C=C and C=O bonds, isomerization of alkenes and hydroformylation of alkenes. The mechanism of isomerization of allyl alcohol to propanal has been elucidated.
