N-phenyl-N'-diisopropoxyphosphinoylcarbodiimide, also known as PDIPC, is a complex organic compound with the chemical formula C15H22NO3P. It is a reagent used in organic synthesis, particularly for the activation of carboxylic acids in the formation of amides and esters. PDIPC functions as a coupling agent, enhancing the reactivity of carboxylic acids by converting them into more reactive species, which can then react with amines or alcohols to form the desired products. N-phenyl-N'-diisopropoxyphosphinoylcarbodiimide is a valuable tool in peptide synthesis and other chemical reactions where the formation of amide or ester bonds is required.

6746-32-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6746-32-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6746-32:
(6*6)+(5*7)+(4*4)+(3*6)+(2*3)+(1*2)=113
113 % 10 = 3
So 6746-32-3 is a valid CAS Registry Number.

SOME TRANSFORMATIONS OF N-(THIO)PHOSPHORYLATED S-ALKYL AND S-ACYLISOTHIOUREAS. SYNTHESIS AND PROPERTIES OF PHOSPHORYLATED CARBODIIMIDES

Kamalov, R. M.,Khailova, N. A.,Pudovik, M. A.

, p. 837 - 841 (2007/10/02)

In the course of vacuum fractionation, N-(thio)phosphoryl-S-allylisothioureas are converted to N-(thio)phosphorylcarbodiimides.These latter were also obtained by elimination of H2S from N-(thio)phosphorylureas under conditions of Appel reaction or by reaction of (thio)phosphoric isothiocyanates with phosphinimine (Staudinger reaction), the latter method giving better results.Reactions of N-thiophosphorylthioureas with acetyl chloride or phenyl isothiocyanate yield mostly thiophosphorylated isothiocyanates, while reactions with chloroformamidine yield both isothiocyanates and carbodiimides.A synthesis is reported of 2-thiophosphoryliminoimidazolidines by reaction of thiophosphorylcarbodiimides with 2-bromoethylammonium bromide.
