Description
C14H17NO4, also known as 4-[[3-(1-Methylethyl)-2-oxo-5-oxazolidinyl]methoxy]benzaldehyde, is an organic compound that serves as an impurity in Bisoprolol, a selective β-adrenergic blocker. It is characterized by its molecular structure, which includes a benzaldehyde core with a unique oxazolidinylmethoxy substituent.
Uses
Used in Pharmaceutical Industry:
C14H17NO4 is used as an impurity in Bisoprolol, a medication for the treatment of hypertension. As a selective β-adrenergic blocker, Bisoprolol helps to lower blood pressure by blocking the action of certain hormones on the heart, leading to a decrease in heart rate and blood vessel constriction. The presence of C14H17NO4 as an impurity in Bisoprolol is significant for quality control and safety assessments in the pharmaceutical manufacturing process.
Check Digit Verification of cas no
The CAS Registry Mumber 1173203-26-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,2,0 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1173203-26:
(9*1)+(8*1)+(7*7)+(6*3)+(5*2)+(4*0)+(3*3)+(2*2)+(1*6)=113
113 % 10 = 3
So 1173203-26-3 is a valid CAS Registry Number.

MANUFACTURE OF BISOPROLOL AND INTERMEDIATES THEREFOR
-
Page/Page column 8, (2010/06/17)
A process for preparing bisoprolol comprises reacting oxazolidinone sulphonate with 4-hydroxybenzylaldehyde to form oxazolidinone benzaldehyde, forming oxazolidone benzylalcohol from oxazolidone benzaldehyde, and subsequently reacting oxazolidinone benzylalcohol with isopropyl oxitol to form bisoprolol base. Oxazolidone sulphonate and oxazolidone benzaldehyde are novel intermediates.
