@Diljith PC , Yes, SSO can be implemented, but it all depends what kind of app you are developing. By that I mean, are you planning to implement OAuth or SAML as the protocols.
Incase you are developing a SAML application, then once the app is developed, you can add that app to Azure AD as a non-gallery app and then configure the SSO for it.
And, incase you are developed the app using ADAL/MSAL that would implement OAuth as the protocol. Using the libraries like either MSAL or ADAL would provide the SSO feature automatically.
Hope this helps.
