General Description

P-hydroxybenzoic acid potassium salt is a white crystalline powder that is commonly used as a food preservative and additive. It is the potassium salt of p-hydroxybenzoic acid, also known as paraben. P-HYDROXYBENZOIC ACID POTASSIUM SALT has antimicrobial properties and is effective in preventing the growth of bacteria and fungi in various products, including food, cosmetics, and pharmaceuticals. It is often added to products such as sauces, jams, syrups, and beverages to extend their shelf life and maintain their quality. P-hydroxybenzoic acid potassium salt is approved for use in food and cosmetic products by regulatory agencies but should be used with caution as high doses have been associated with potential health risks.

Check Digit Verification of cas no

The CAS Registry Mumber 16782-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,8 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16782-08:
124 % 10 = 4
So 16782-08-4 is a valid CAS Registry Number.

An Anionic, Chelating C(sp3)/NHC ligand from the Combination of an N-heterobicyclic Carbene and Barbituric Heterocycle

The coordination chemistry of the anionic NHC1-based on an imidazo[1,5-a]pyridin-3-ylidene (IPy) platform substituted at the C5 position by an anionic barbituric heterocycle was studied with d6(Ru(II), Mn(I)) and d8(Pd(II), Rh(I), Ir(I), Au(III)) transition-metal centers. While the anionic barbituric heterocycle is planar in the zwitterionic NHC precursor 1·H, NMR spectroscopic analyses supplemented by X-ray diffraction studies evidenced the chelating behavior of ligand 1-through the carbenic and the malonic carbon atoms in all of the complexes, resulting from a deformation of the lateral barbituric heterocycle. The complexes were obtained by reaction of the free carbene with the appropriate metal precursor, except for the Au(III) complex 10, which was obtained by oxidation of the antecedent gold(I) complex [AuCl(1)]?with PhICl2as an external oxidant. During the course of the process, the kinetic gold(I) intermediate 9 resulting from the oxidation of the malonic carbon of the barbituric moiety was isolated upon crystallization from the reaction mixture. The νCOstretching frequencies recorded for complex [Rh(1)(CO)2] (5) demonstrated the strong donating character of the malonate-C(sp3)/NHC ligand 1-. The ruthenium complex [Ru(1)Cl(p-cymene)] (11) was implemented as a precatalyst in the dehydrogenative synthesis of carboxylic acid derivatives from primary alcohols and exhibited high activities at low catalyst loadings (25-250 ppm) and a large tolerance toward functional groups.
