23602-61-1 Usage
General Description
3,4-Dichloro-2-hydroxybenzaldehyde is a chemical compound with the molecular formula C7H4Cl2O2. It is a white to light yellow solid that is used in the synthesis of pharmaceuticals and agrochemicals. 3,4-Dichloro-2-hydroxybenzaldehyde is often used as an intermediate in the production of various other substances, including dyes and pigments. It has a characteristic aromatic odor and is soluble in organic solvents such as ethanol and acetone. The presence of chloro and hydroxy groups in its structure makes it a versatile building block for the synthesis of a wide range of organic compounds. However, it should be handled with caution as it is a potential irritant to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 23602-61-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,0 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23602-61:
(7*2)+(6*3)+(5*6)+(4*0)+(3*2)+(2*6)+(1*1)=81
81 % 10 = 1
So 23602-61-1 is a valid CAS Registry Number.

Extending the stetter reaction with 1,6-acceptors
Law, Katherine R.,McErlean, Christopher S. P.

Pace Stetter: A new N-heterocyclic carbene (NHC)-catalysed transformation is described-the intramolecular vinylogous Stetter reaction. This transformation can be effected with both thiazolium and triazolium-based catalysts, using aromatic and aliphatic aldehydes, employing α,β,γ,δ- unsaturated esters, ketones, phosphonates and N-acylpyrroles, and can be conducted enantioselectively (see scheme).

Salicylaldoxime moiety as a phenolic "A-ring" substitute in estrogen receptor ligands
Minutolo,Bertini,Papi,Carlson,Katzenellenbogen,Macchia
, p. 4288 - 4291 (2007/10/03)
The phenolic "A-ring" of natural and synthetic estrogen receptor (ER) ligands was effectively replaced by a planar six-member ring formed through an intramolecular hydrogen bond within a salicylaldoxime. Thus, oxime 1, a structural analogue of a triarylet
