Uses

Used in Research and Diagnostic Laboratories:
H-ALA-ONP HCL is used as a tool for studying enzyme kinetics and evaluating the effectiveness of potential enzyme inhibitors. Its ability to produce a color change upon enzyme action makes it a valuable resource for researchers and diagnosticians to assess enzyme activity levels and the impact of inhibitors on these activities.
Used in Biochemical Assays:
In biochemical assays, H-ALA-ONP HCL is used as a substrate for detecting and measuring the activity of various enzymes, particularly those that hydrolyze ester bonds. H-ALA-ONP HCL's chromogenic properties allow for the visual assessment of enzyme activity, providing a straightforward and reliable method for such analyses.
Used in Enzymatic Assays:
H-ALA-ONP HCL is also utilized in enzymatic assays to determine the presence and activity of specific enzymes. The yellow color produced when the p-nitrophenyl ester group is cleaved by the enzyme serves as a clear indicator of enzymatic activity, making H-ALA-ONP HCL an essential component in these assays.

Check Digit Verification of cas no

The CAS Registry Mumber 17463-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,6 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17463-53:
(7*1)+(6*7)+(5*4)+(4*6)+(3*3)+(2*5)+(1*3)=115
115 % 10 = 5
So 17463-53-5 is a valid CAS Registry Number.
