Description

3-METHYLPENTANE-1,3,5-TRIOL, also known as 3-Methyl-1,3,5-pentanetriol, is an organic compound with the molecular formula C6H14O4. It is a triol, meaning it contains three hydroxyl (-OH) groups attached to a carbon chain. 3-METHYLPENTANE-1,3,5-TRIOL is known for its versatile chemical properties and is commonly used as a building block in the synthesis of various organic compounds.

Uses

Used in Pharmaceutical Industry:
3-METHYLPENTANE-1,3,5-TRIOL is used as an intermediate in the synthesis of Mevalonolactone (M339040) for its potential therapeutic applications. Mevalonolactone is a key compound in the mevalonate pathway, which plays a crucial role in the biosynthesis of cholesterol, dolichols, ubiquinones, and isoprenoid compounds. Its potential use in the development of drugs targeting this pathway makes 3-METHYLPENTANE-1,3,5-TRIOL an important precursor in the pharmaceutical industry.
Used in Vitamin and Isoprenoid Synthesis:
3-METHYLPENTANE-1,3,5-TRIOL is used as a starting material in the synthesis of vitamins and isoprenoids, such as steroids. Isoprenoids are a large and diverse class of natural organic compounds derived from isoprene units, and they play essential roles in various biological processes, including cell signaling, membrane integrity, and energy production. Vitamins, on the other hand, are essential nutrients required for various metabolic processes in the body. The ability of 3-METHYLPENTANE-1,3,5-TRIOL to be converted into these vital compounds highlights its importance in the chemical and pharmaceutical industries.

Check Digit Verification of cas no

The CAS Registry Mumber 7564-64-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,6 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7564-64:
(6*7)+(5*5)+(4*6)+(3*4)+(2*6)+(1*4)=119
119 % 10 = 9
So 7564-64-9 is a valid CAS Registry Number.

Described herein polymer precursor compounds (aka polymer building blocks) of derived from biobased compounds, and specifically biobased mevalonolactone and its related derivatives. Through oxidation these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols and polyamides, as well as precursors for glycidyl esters and omega-alkenyl esters. Through reduction, these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols, polycarbonates, as well as precursors for glycidyl ethers and omega-alkenyl ethers. Through nucleophilic ring opening and/or amidation, these biobased precursors can be reacted to yield building blocks for polyester polyols, chain-extender for polyurethanes, or polyester-amides.

Cu/nitroxyl catalysts have been identified that promote highly efficient and selective aerobic oxidative lactonization of diols under mild reaction conditions using ambient air as the oxidant. The chemo- and regioselectivity of the reaction may be tuned by changing the identity of the nitroxyl cocatalyst. A Cu/ABNO catalyst system (ABNO = 9-azabicyclo[3.3.1]nonan-N-oxyl) shows excellent reactivity with symmetrical diols and hindered unsymmetrical diols, whereas a Cu/TEMPO catalyst system (TEMPO = 2,2,6,6-tetramethyl-1-piperidinyl-N-oxyl) displays excellent chemo- and regioselectivity for the oxidation of less hindered unsymmetrical diols. These catalyst systems are compatible with all classes of alcohols (benzylic, allylic, aliphatic), mediate efficient lactonization of 1,4-, 1,5-, and some 1,6-diols, and tolerate diverse functional groups, including alkenes, heterocycles, and other heteroatom-containing groups.

A range of putrescine and cadaverine derivatives has been synthesized and assayed as substrates for the diamine oxidases from pea seedlings and pig kidney. KM and Vmax data are reported, mainly for the pea enzyme. N-Alkylputrescines and C-alkylcadaverines are generally poorer substrates than the parent compounds with up to 4500-fold reduction in Vmax. There is significantly less variation in KM values, indicating that the binding site of the pea enzyme is relatively non-specific and that enzymic specificity lies at the catalytic stage. This suggests that poor substrates might act as convenient, short-lived inhibitors of diamine oxidases.
