Palmitic acid-(4-nitro-benzyl ester) is a chemical compound derived from palmitic acid, a saturated fatty acid with a 16-carbon chain. In this ester, the carboxylic acid group of palmitic acid is esterified with 4-nitrobenzyl alcohol, resulting in a molecule that combines the properties of both components. The 4-nitrobenzyl group introduces a nitro substituent on the benzene ring, which can be used as a protecting group in organic synthesis or as a functional group for further chemical reactions. This ester is often employed in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique reactivity and stability.

Check Digit Verification of cas no

The CAS Registry Mumber 4457-36-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4457-36:
(6*4)+(5*4)+(4*5)+(3*7)+(2*3)+(1*6)=97
97 % 10 = 7
So 4457-36-7 is a valid CAS Registry Number.

Trimethylamine-Borane a Useful Reagent in the One-Pot Preparation of Carboxylic Esters from Carboxylic Acids

Trapani, Giuseppe,Reho, Antonia,Latrofa, Andrea,Liso, Gaetano

, p. 853 - 854 (1990)

The carboxylic esters 2a-h (R1CO2CH2R1) and 4a-d (R1CO2CH2R2) are synthesized from alkyl or aryl carboxylic acids, a one-pot reaction involving in situ reduction followed by esterification, both steps are mediated by trimethylamine-borane.
