1320-06-5 Usage

Physical properties

Solvent Red 27 is a dark green to dark brown crystalline powder.

Uses

Different sources of media describe the Uses of 1320-06-5 differently. You can refer to the following data:
1. Oil Red O is suitable as a lipid and lipoprotein stain on cellulose acetate. It is one of the diazo dyes used for staining of neutral triglycerides and lipids. It is used to analyze muscle fibers. It acts as an agent that stains lipids, muscle fibers and alveolar macrophages. Further, it is also used as marking dye. It is an active component of red colored smokes in pyrotechnics.
2. Oil Red O has been used for the staining of lipid droplets and lipid-containing vacuoles in cells.

Preparation

2-Amino-2′,3,4′,5-tetramethylazobenzene diazotization, and Naphthalen-2-ol coupling.

General Description

Oil Red O stains lipid materials and imparts red-orange color to the lipids. It also marks vacuoles, particularly observed in ALL-L3 (acute lymphoblastic leukemia) or Burkitt′s lymphoma/leukemia. Oil Red O staining is done on fresh samples, as alcohol fixation removes lipids.

Properties and Applications

blue light red. Soluble in ethanol for yellow red, soluble in acetone, soluble in benzene. In concentrated sulfuric acid to green light blue, blue purple precipitation after dilution.

Check Digit Verification of cas no

The CAS Registry Mumber 1320-06-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1320-06:
(6*1)+(5*3)+(4*2)+(3*0)+(2*0)+(1*6)=35
35 % 10 = 5
So 1320-06-5 is a valid CAS Registry Number.
