It is usually supplied as its red sodium salt but can also be used as the calcium and potassium salts. These salts are soluble in water. In solution, its maximum absorbance lies at about 504 nm. [3]: 921 Allura Red AC is manufactured by azo coupling between diazotized 5-amino-4-methoxy-2-toluenesulfonic acid and 6-hydroxy-2-naphthalene sulfonic ...
Sodium 1,3-dithiole-2-thione-4,5-dithiolate is the organosulfur compound with the formula Na 2 C 3 S 5, abbreviated Na 2 dmit. It is the sodium salt of the conjugate base of the 4,5-bis(sulfanyl)-1,3-dithiole-2-thione. The salt is a precursor to dithiolene complexes and tetrathiafulvalenes. [1] Reduction of carbon disulfide with sodium affords ...
Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O − 2) anion radical into normal molecular oxygen (O 2) and hydrogen peroxide (H 2 O 2). Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. [2]
Superoxide dismutase 2, mitochondrial (SOD2), also known as manganese-dependent superoxide dismutase (MnSOD), is an enzyme which in humans is encoded by the SOD2 gene on chromosome 6. [5] [6] A related pseudogene has been identified on chromosome 1. Alternative splicing of this gene results in multiple transcript variants. [5]
It is made from four parts: a capsule holder wrapped with cloth or other soft material, a small plastic capsule containing 0.88 grams of sodium cyanide, a spring-powered ejector, and a 5–7 inches (130–180 mm) stake. To install the trap, the stake is first driven down into the ground, and then the capsule is put in the holder, screwed onto ...
Bioglass 45S5 or calcium sodium phosphosilicate, is a bioactive glass specifically composed of 45 wt% SiO 2, 24.5 wt% CaO, 24.5 wt% Na 2 O, and 6.0 wt% P 2 O 5. [1] Typical applications of Bioglass 45S5 include: bone grafting biomaterials , repair of periodontal defects, cranial and maxillofacial repair, wound care, blood loss control ...
Eutectic alloys for soldering, both traditional alloys composed of lead (Pb) and tin (Sn), sometimes with additional silver (Ag) or gold (Au) — especially Sn 63 Pb 37 and Sn 62 Pb 36 Ag 2 alloy formula for electronics - and newer lead-free soldering alloys, in particular ones composed of tin, silver, and copper (Cu) such as Sn 96.5 Ag 3.5.
It reacts with malononitrile to form 2-imino-6-methoxy-2H-1-benzopyran-3-carbonitrile. [2] It can be reduced by sodium borohydride in ethanol to form 2-hydroxy-5-methoxybenzyl alcohol. [ 3 ]
