148823-36-3 Usage
General Description
H-D-ASP-OTBU is a chemical compound consisting of Nα-Fmoc-Nδ-OtBu-D-aspartic acid, a protected form of the amino acid aspartic acid. The compound is commonly used in the synthesis of peptides and proteins, as the tert-butoxycarbonyl (OtBu) and 9-fluorenylmethoxycarbonyl (Fmoc) groups protect the aspartic acid residue from premature coupling reactions and side reactions during peptide synthesis. H-D-ASP-OTBU is known for its stability and compatibility with solid-phase peptide synthesis, making it a valuable tool in the production of bioactive peptides and pharmaceuticals.
Check Digit Verification of cas no
The CAS Registry Mumber 148823-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,8,2 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 148823-36:
(8*1)+(7*4)+(6*8)+(5*8)+(4*2)+(3*3)+(2*3)+(1*6)=153
153 % 10 = 3
So 148823-36-3 is a valid CAS Registry Number.

Ophthalmic liposomes
-
, (2008/06/13)
A liposome composition with enhanced retention on ocular surfaces, for use in ophthalmic drug delivery and dry eye treatment. The liposomes contain about 10-40 mole percent of an amine-derivatized lipid component in which a charged amine group is spaced from a lipid polar head region by a carbon-containing spacer arm at least 3 atoms in length. The liposomes preferably have a close packed lipid structure produced by inclusion of between 20-50 mole percent of cholesterol or an amine-derivatized cholesterol, and/or phospholipids with predominantly saturated acyl chain moieties. The liposomes may be suspended in an aqueous medium containing a high-viscosity polymer, formulated in paste form, or embedded in a polymer matrix, to enhance further the retention of liposomes on a corneal surface.
